I have no Gexdulkd - and so I bought despite very different reviews these home-cinema system. Haste was necessary, because the matching TV I had also just bought :) And so I had a first offense indicated: The plant has only analog connectivity - the TV luckily digital and analog also. So such a policy finally worked the connection. And sure it's true, especially when in the high registers Säulenlautsprcher somehow a little crackle. But if you the sound is then surrenders the sound much better than the one that comes from the original speakers of the TV and you have a very nice surround sound. For just over 100 euros you have not done much wrong with the purchase. Systems that ensure a clear sound to bring more performance, also require a much deeper grip in the wallet!
